Parallel two low amp cables to make one big
I am looking to increase my panel size from 20 amp max to 40 amp max. I have a good amount of 25 amp cable so am wondering if it is OK to parallel another 25 amp cable alongside my existing installation.
760W panel array, 4 x 6v 220 ah Crown batteries, Tristar TS-45 PWM controller, no name 600 PSW inverter.
